Abstract
The utility model relates to an equipotential connection box for an electric installation in a building. The equipotential connection box comprises an installation box (1), a wire connecting terminal (2) and a protective panel. The wire connecting terminal (2) is arranged on an inside convexity at the middle part of the installation box bottom. Knock-off holes (4, 6) are arranged on the side surfaces of the installation box and are corresponded to a connection wire and a flat conductor connection of the wire connecting terminal. One part of the cuboid wire connecting terminal is grooved for the flat conductor to be connected in and for a tightening bolt (3) to be arranged in; the other part of the cuboid wire connecting terminal is opened with connection holes (8) which are symmetrically arranged oppositely by two or more than two, and a wire-pressing bolt (5) is arranged at the upper part of the connection hole. The protective panel is arranged on the top of the installation box (1). The utility model is convenient in operation, safe and security, beautiful and practical.
Description
Technical field
The utility model relates to the equipotential termination that a kind of architectural electricity is used, mainly be applicable to the potential difference that reduces between interior indirect contact voltage of building and different metal parts, and can eliminate from building the place of beyond the region of objective existence through the risk of disturbance voltage harm of electric wiring and the introducing of various metallic conduit.
Technical background
Present still in recent years thing of the introducing of the relevant equipotential bonding technology in building's electrical design aspect at home.Because this top technology relates to the requirement of building to people's life security, is subject to people's attention just day by day.International and domestic relevant criterion and the parameter of successively having formulated relevant equipotential termination technology, as international electrical engineering standard IEC60364-4-41,<<" civil buildings electrical design standard " (JGJ/T16-92), " Code for design of dwelling houses " (GB50096-1999), " equipotential bonding installation " (97SD567) etc.But the terminal box volume of existing equipotential termination is big, loads onto the copper bar in several holes on one section brill in the can, with the incoming line screw placement terminal box together of screwing on, makes coarsely, and poor reliability is used inconveniently, and outward appearance is not attractive in appearance yet.
Summary of the invention
The utility model has overcome existing equipotential terminal box poor reliability, has used inconvenience, and the defective that outward appearance is coarse provides a kind of equipotential termination, and this device is esy to use, safe and reliable, both artistic and practical.
The utility model is achieved in that a kind of equipotential termination, comprise mounting box, binding post and protection face board, stage casing, mounting box bottom is interior convex surface, on the interior convex surface binding post is installed, mounting box has knock down hole on four sides, knock down hole inserts corresponding with the tie-in line and the flat conductor of binding post, binding post is rectangular-shaped, half fluting of binding post cuboid is in order to insert flat conductor, cuboid groove one upper lateral part has dress housing screw in the screw, second half has wiring hole the binding post cuboid, wiring hole is more than two or two and bi-directional symmetrical is arranged, wiring hole top correspondence has dress line pressing bolt in the screw, and protection face board is stamped at the mounting box top.
Above-mentioned equipotential termination has on three sides of mounting box of described terminals pilot trench end correspondence and inserts the knock down hole that flat conductor is used, and two sides of the mounting box of binding post wiring nose end correspondence have the knock down hole that tie-in line is used.
Above-mentioned equipotential termination, described housing screw and line pressing bolt bottom are spherical interior hexagonal holding screw.
The utility model adopts end fluting to insert flat conductor and the other end is the binding post that two-way wiring hole inserts lead, and insert and the corresponding mounting box that has knock down hole of wiring hole tie-in line with the flat conductor of binding post, can satisfy the requirement of two side inlet wires and three side access flat conductors.Half inserts flat conductor binding post, and second half is a wiring hole, unidirectionally inserts three leads, two-wayly can insert six conductors at most.The housing screw that compresses flat conductor and tie-in line that uses on the binding post and the bottom of line pressing bolt are spherical interior hexagonal holding screw, have crimping and firmly, do not hinder lead, prevent the advantage that the layman operates without authorization.Mounting box adopts the die stamping one-shot forming, and is handsome in appearance, around the box body knock down hole arranged, easy to use.
Description of drawings
Fig. 1 is the utility model structural representation, and Fig. 2 is the side sectional view of Fig. 1, and Fig. 3 is Fig. 1 partial sectional view.
Among the figure: 1 mounting box, 2 binding posts, 3 housing screws, 4 flat conductor knock down holes, 5 line pressing bolt, 6 tie-in line knock down holes, 7 terminals pilot trench (or cuboid groove), 8 binding post wiring holes, 9 screws.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of equipotential termination comprises mounting box 1, binding post 2 and protection face board.Stage casing, mounting box 1 bottom is interior convex surface, with screw 9 binding post 2 is installed on the interior convex surface.Binding post 2 is rectangular-shaped, and half fluting 7 of binding post 2 cuboids is in order to insert flat conductor, and cuboid groove 7 one upper lateral parts have dress housing screw 3 in the screw, in order to compress flat conductor; Second half has wiring hole 8 binding post 2 cuboids, and wiring hole 8 is more than two or two and bi-directional symmetrical is arranged, and the wiring hole 8 of present embodiment is three of rows, and opposite side also is three of rows, and bi-directional symmetrical is arranged, and inserts two-way six conductors at most like this.If mounting box 1 is a cuboid, then binding post 2 can lengthen, and wiring hole 8 can increase.Wiring hole 8 top correspondences have dress line pressing bolt 5 in the screw.Housing screw 3 and line pressing bolt 5 bottoms are spherical interior hexagonal holding screw, have crimping and firmly and not hinder lead, prevent that the layman from operating without authorization.Protection face board is stamped at mounting box 1 top.Have knock down hole on the side around the mounting box 1, knock down hole inserts corresponding with the tie-in line and the flat conductor of binding post 2, be to have on 1 three sides of mounting box of binding post 2 flat conductor incoming end correspondences to insert the knock down hole 4 that flat conductor is used, two sides of the mounting box 1 of binding post 2 bi-directional arrangement wiring nose end correspondences have the knock down hole 6 that tie-in line is used.Flat conductor three directions from the side inserts binding post 2, and tie-in line also can insert binding post 2 from two side surface direction, greatly facilitates user's use like this.
